1. 1. Tencent Hunyuan Hy3: 295B MoE Serving 1B+ Users

   Tencent Hunyuan's Hy3: 295B total, 21B active MoE. Inference efficiency matches 2-5x larger models. Agent-oriented LLM integrated into WeChat serving 1B+ users.

2. 2. GPT-5.6 Sol Ultra Proves 50-Year Graph Theory Conjecture

   OpenAI's GPT-5.6 Sol Ultra produces a complete proof of the Cycle Double Cover conjecture in under an hour. The problem stood for 50 years.

3. 3. Apple Sues OpenAI for Poaching 400, May Cripple Hardware Plans

   Apple alleges OpenAI poached 400 employees, stole engineering devices and confidential files. Analysts say hardware plans may suffer even if unproven.

4. 4. Codex & ChatGPT Work Remove 5-Hour Limit

   OpenAI temporarily removes 5-hour usage limit for all Plus, Business, and Pro plans. Rolling out changes to make GPT-5.6 Sol available in Work.

5. 5. Nadella Proposes 'Reverse Information Paradox'

   Microsoft CEO warns companies expose proprietary knowledge when using AI, creating 'intellectual exhaust' that trains models. Calls for real data protection.

6. 6. Mesh LLM: Open-Source Distributed AI Computing

   Mesh LLM pools GPU and memory across machines, exposing OpenAI-compatible API. Peer-to-peer via iroh networking, no central server needed.

7. 7. xAI Grok Build Uploads All Files, Privacy Concerns

   Network analysis reveals Grok Build CLI sends plaintext file contents (including .env secrets), full git history, and repo descriptions to xAI servers.

8. 8. Altman Pivots: AI Is Net Job Creating

   Sam Altman now 'pretty sure' AI has net created jobs, admitting it's not what he expected. Previously warned AI's impact might be 'scary fast.' Anthropic CEO also revises stance.

9. 9. Open-Source Models Face 6-Month Survival Test

   White House considers executive order to regulate open-source models, potentially banning releases approaching GPT-5.5-level capabilities within 6 months.

10. 10. Mindwalk: 3D Code Map Replay for Coding Agents

    Mindwalk visualizes Claude Code and Codex sessions on a 3D codebase map. Repository renders as a night map: files touched by agents glow, untouched areas stay dark.
